Specification of Letters Patent.

Patented Jan. 21, 1913.

Application filed May 10, 1912. Serial No. 696,478.

To all whom it may concern:

Be it known that I, RODERICK D. COLE- MAN, a citizen of the United States, residing at Greenwood, in the county of Albemarle and State of Virginia, have invented new and useful Improvements in Cattle-Guards, of which the following is a specification.

This invention relates to improvements in cattle guards and the object of the invention is to provide a simple and efficient structure of this character adapted for closing the passage way across the track, the gates being normally maintained automatically in closed position and opened by a train approaching in either direction.

Further objects of this invention will appear as the following specific description is read in connection with the accompanying drawing, which forms a part of this application, and in which Figure 1 is a perspective view. Fig. 2 is an elevation with the gates in open position and with parts broken away.

Referring more particularly to the drawings, 1 represents suitable uprights which are located upon opposite sides of the track and provided at their upper ends with horizontally extending ears 2 provided with vertical apertures 3. The posts of the gate are indicated at 4: and are provided adjacent their upper ends with heads 5 having spiral grooves formed therein. These heads are adapted to move freely through the vertical apertures in the members 2 and have their grooves engaged by inward projections 6 which are rigid with the members 2 and cause the gate posts to revolve, as will be clearly understood, when said posts are elevated. These gates each comprise the horizontally extending bars 7 which are secured at one end to the posts 1 and at their opposite ends are connected to the bar 8, which is connected to the upper ends of the heads 5, as shown at 10. This portion 10 of the rod 8 has an extension which projects beyond the heads 5 and is engaged with a vertical slot formed in the plate 12 secured upon the top of the members 2, thus providing a latching means for preventing movement of the gates until the same have been raised, as will be hereinafter described.

Pivoted at one end adjacent the rail of the track 9 on either side of the gate are the levers 13 which extend longitudinally of the track and work in guides 14' secured to the ties. At their inner or meeting ends, these levers 33 are provided with depending links 15 which connect with the inner ends of levers 16, and 20, as shown in Figs. 1 and 2. The levers 16 and 20 are pivoted adjacent their inner ends to bifurcated posts 17 which are secured in the ground or to a base board extending under one rail of the track. The outer end of said levers are reduced and move in vertical slots 18 formed in the uprights 1. These levers are connected directly to the gate posts 1 by means of yoke members 19 which project downwardly from said posts 4, as shown.

When the gates are closed, the tripping levers 13 are raised at their inner ends, and

when the train approaches its wheels will engage said levers and depress the same. The inner ends of the levers l6 and 20 will be correspondingly depressed and the opposite ends of the levers which carry the gate post will be raised accordingly. This action will elevate the latching extensions on the members 10 out of engagement with the slots in the plates 12 and through the medium of the projections within the vertical passages 3 and the spiral grooves upon the heads 5, the gate sections will be rotated and turned out of the way of an approaching train. As soon as the train has passed and its wheels disconnected from the tripping levers upon the opposite side of the gate, the weight of the gate sections causes the parts to be returned to normal position with the operating or tripping levers in operative position for the passage of the next train in either direction.

What is claimed is 1. The combination, of uprights located on opposite sides of the track, gate sections movable thereon, of bars pivoted at their outer ends and adjacent the rail of the track and extending longitudinally of the same, links depending from the meeting ends of said bars, levers pivoted adjacent their inner ends to supports raised from the ground, one of said levers being forked at its outer end and the end of the opposite lever adapted to extend between said forked ends and be pivoted therein, said meeting ends of the levers being also pivoted to the depending links, the opposite ends of the levers moving in slots formed in the uprights adjacent their lower ends, pivotal connections between the levers and the posts of the gate sections, whereby when the operating bars are depressed, the gate sections will be raised,

swinging of the gates until raised and operated, means for raising the gate whereby the same Will be rotated and the latching mechanism disconnected.

In testimony whereof I affix my signature in presence 01 two Witnesses.
